BIAS TAPE AND eeocess O MAKING THE SAME.

. EPEGIFICATION forming part of Letters Patent No. 293,440, datedFebruary 12, 188.*

Application filed December 4, 1882. (No model.) I

To all whom it may concern:

Be it known that I, CHARLES H. FARMER, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Bias Tape andProcess of Making the Same; and I do hereby declarethat the same arefully described in the following specification, and illustrated in theaccompanying drawings.

The object of this invention is to produce a perfect article of biastape formed in continuous strips of bias-cut fabric put up in packagesready for use, and adapted .for bindings, pipings, and the like; andalso to provide a process by which the production of such article isgreatly facilitated and cheapened. The drawings illustrate certain stepsof the process which I employ, and show also the article put up in itsmerchantable form.

Figure 1 represents aseetion of the original fabric cut obliquely to itswarp and filling, which areindicated by the shade-lines. Fig. 2 showssuch sections united at their selvages into a band, the shade-lines notindicating the direction of theinterwoven threads. Fig. 3 shows, on alarger scale, this band wound on apasteboard core, and also a stick ofthe continuous tape cut therefrom with its core; and Fig. 4 represents acylindrical coil of my bias tape. I I

In the manufacture of my improved tape, I proceed as follows: I take anysuitable woven fabric-such as cotton cloth or muslin-of the ordinarywidths, and cut it on a true bias of forty-five degrees to its lengthinto parallelograms A, of convenient and uniform size. These pieces Iunite into a continuous band, B, by rubber cement or some equallypowerful and pliable adhesive substance applied to the sel vages w ofeach piece, and exposed untilthe naphtha or'other solvent has evaporatedsuffi ciently for the pieces to adhere at saidedges by pressure. Thesecemented joints 0 will therefore run obliquely across the band, as inFigs. 2 and 3, and its marginal edges, b,will be the raw edges where theoriginal fabric was severed, (see at b, Fig. 1.) The band, so formed ofsuccessive rhombic figures, and having a succession of pliable cementedjoints (3 r where said pieces are united by their selvages,

gles to the edges of the pasteboard core,which core is itself out by theoperation into disconnected strips, while each'cutting severs a lengthof tape equal to the full length of the band, and having at intervalsthe pliable cemented joints 0 described, and at all points the true biasarrangement of the fabric incident to this 0011- This cutting of theband B into continuous lengths of tape is best effected by an ordinarypaper-cutting machine, having a' fiat bed to support the material heldin place upon it, and a reciprocating cutter making a drawing stroke.NVith such a machine I lay the band to be out upon a thick pasteboardsheet, which the cutting-blade may readily sever, and I clamp to thetable a barrier of similar material to support the front edge of thefolded band against the thrust of the out ting-knife. Bythese means,while I out to waste the core in the band, the sheet beneath it, and thebarrier in front of it, Isecure at each stroke of the cutter a true anduniform stick of bias tape of thirty-six or seventy-two yards length, asthe case may be, with edges p el fectly matched at each joint, andpliably united to the extreme edges, so as to make finished work whichwill pass through the sewing-machine attachments without interri'iption.The strip of the core D, which is severed with the stick of tape, forms,as it were, an elongated spool to hold the tape wound upon it inmerchantable shape, or the tape may be coiled into cylindrical rolls forgreater convenience in use. (See Fig. 4.)

I am aware that it is the practice of dress makers and others to cutfabrics bias for bindings, trimmings, 8750., and that such bias-cutdisconnected strips have been heretofore made and sold to be connectedby stitches when applied to a garment or other article; and, also, thatseparately-cut bias strips of trimming width have been successively andsingly stitched together endwise, and subsequently embroidered. I makeno claim to any of these things, since it is essential to my process andits product that the series of joints be formed before the tape is cutfrom the broad band.

I claim as my invention 1. As anew article of manufacture, bias tape putup in sticks or rolls and formed of uniforn; width in continuous lengthsof fabric, with a succession of pliable oblique and paralleljointshaving perfectly-matched cut edges, Without projecting threads,substantially as set forth.

2. The improved process of making continuous bias tape, consistingincutting the fabric at an'angle of about forty-five degrees to its
